ffl/PLIANCE non ATTACHINQBUMPERS ADJUSTABLE! To AUTOMOBILES. IApplication filed November 13, 1922.' Serial No. 609,527. *c '/f l l I l'gp/'- To all whom z'may concewz: 4 varies accordingly. In general,the/length 'e't known that I, Hmmm G; Cox, u citizen of the UnitedStates, residingat leveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements, in an Appliancefor Attaching Bumpers Adjustably to Automobiles',of which thefollowingis a speciication. l0

attaching a bumper edjustably to an automobile chassis freine, the nieinobject being construction which will permit facile ettachments to bemade to ch ties of different shape and form end to spring bolts ofdifferent diameter, and which also y adjusteblyso that its' impact facemay be setand i o I u v ln the accompanying drawings, Fig. 1 is a top`view of the curved end of one side inempresented squarely c e.

parts shown in Fig. 1, the umper bar being m section, and the shacklebolt and nut being partly broken away. Fig. 3 isn verticali section online 3--3 of F'gr. 1, end 1 iso horizontal section on line 4`4: of Fig'.2. Fig. 5 is a perspective View of the cleifnping,r segment.

the ,make or the t 1n many instances be too short te perpiece ofsubstantial thickness such as a bracket member 8, to he boltV ed againstthe freine extremity and have all o the screw-threads inthe. nut engagethe screw threads on the bolt. I h devised an arrangeinent whereby thepresent bolt may be used to mak i e seme time, permit the bracket memberto be ettached 'Herent diameters. h

bolt 16 or an equivalent clamping device to be is bent downwardly, andhas e single relatively large round` bolt opening 17 'therein whichopens into a concentric .round recess 18 in th of thegirin, andthe boltopemngis relazrely much larger in diameter than the iai-gest shacklebolts ir?. common use so that the boit is separated from the bracket yun annular space when the bolt extends through this opening. Howeneigall loose play is eliminated byemployn'g' special hexagonal nut 19having e"round.freduced portion or tielly th to lit therein and providee bearing-rior the arm 14 when th The split e' flange 10 of the llowstherefore` ave howeverA e an absolutely `secure connection and at th itsextremity to.

e outer fiat side extension 20 which is of substan- 1 esame diameter asopening 17 so es,...-". .ew is nut is screwed f A lock 'washer955ssleeved over the round extensionf2G :ofthe nut and is seated at thebase of theroundi cavity or recess 18 when 'the .mit is serevved" 7,'especially the sus enn threads may be used in making a screw-con nectionWithout changing or removing the standard bolt forming a part of theregular equipment ofthe vehicle. tage because it avoids disassemblingthe hook-up for the spring, and also replacement ot special bolts, manyof these bolts being specially lricade for receiving oil or to conveyoil from cups or oil attachments. A still further advantage resides inthe 'facile way whereby7 one standard size oi' bracket member may bei'itted to any car, large or small. having large or small shackle bolts.Thus. in Figs. 6 to 10, inclusive, l. show three shackle bolts, a, andc, having screwlthreaded ends of different diameters but the respectivebracket arms 14 are alike, havingr the same sized bolt openings 17 andrecesses 18. The, nuts d, e and f. differ from each other only in thattheir central screwthreaded openings conform to the screwtlneaded endportions of the bolts of which they lorm complementary parts. v Theround extensions .20 of these nuts are all o't the same diameter so astouse the saine size lock washers and to permit these extensions toenter and have a bearingr tit within the round openingY 17 in anybracket arm 14. constructed according' to my invention.

Bracket member R ai'ljustaloley angularly in respect to the cliassistrame 2 by reason ot the four bolt holes 15 and :ittaclnnent bolt 1d butthis adjustment is limited and muy not always permit the bumper ll to beplaced squarely with its dat vertical impact face in a perpendicularplane` especially it' the. bumper has a broad impact face or is of theloop type or of the multiple bar kind. l therefore. produce a verticalcurvature Q1 in a segmental. portion ot the cirei'ilar loop 11 otbracket 8; that is to say. the iiat` bar i'orining this bracket ispressed into n concaveeonvex forn'r at the iront oi loop 11 to permit .acircular segment 2Q to be seated rotatably at the front side of thebracket and to be clampeil adjustably in place thereon to getiier with abumper bar li by ineans of a llbolt 23, a clip 2l. and .nuts 25. Segment22 has a central groove Lio in its` circular clamping side whichprovides twospaced seating faces 27--27 and also notched ends Z8-285 thelatter serving as guides l'or the lThis is of advanstraight legs ofU-bolt 23 and to hold the said segment from lateral displacement whenfitted between the legs of the U-bolt. To promote adjustment andclamping the yoke portion 29 of the U-bolt may also be curved to conformto the vertical curvature of the front seating portion o the bracket. Itshould also be understood that in attaching a bumper to a chassis frame,complementary Sets ot the attachment devices are used at opposite sidesof the chassis frame, and the bumper may be a spring bar bumper or anyother type of bumper or buffer capable of being c amped in placesubstantially as herein shown and descrid.

What l claim is:

1. A loop-shaped bracket having rearwardly extending attachment arms anda concave-convex -liront portion, a rounded clamping segment seatedwithin the concaved side, of said front portion, and a yokeshapedclamping device and associated clampingr means adapted to secure abumper and said segment jointly together in rotatable adjustableposition upon said bracket.

2. A loop shaped bracket having a long,r rearwardly-eXtending attachmentarm and a short downwarally-extendingV attachment arm and the loophavingy a horizontally-eir tending concaved portion at the frontthereol, in combination with a rounded clamping' segment seated Withinsaid eoncaved portion of the loop. a 'L-b .t encircling said conearedportion of the loop opposite said segment, a bumper clamping memberadjustably engaged with said U-bolt at the front of said segment, andnuts on said bolt engaging said clamping member.

3. loop-.shaped bracket made of iiat strap-metal havin T a long armprovided with bolt openings and a short arm provided with a round recessin its outer side and a round bolt openinio)` centrally at the base ofsaid recess, the front portion of the loop being concavo-convexvertically to receive a rounded bumper clamping element and to provide arounded rear-clamping surface for a yokeshaped c ainpingr member.

In testimony whereof l aii'ix my signature hereto.
